Irura yueluensis (Peng & Yin 1991) and Synageles hilarulus (C. L. Koch 1846) (Araneae: Salticidae), new to Japanese fauna

Abstract

Two salticid species, Irura yueluensis (Peng & Yin 1991) and Synageles hilarulus (C. L. Koch 1846) are newly recorded from Japan. The genus Irura is also new to Japan, and I. yueluensis is the single Japanese species at the present. This genus can be distinguished from other salticid genera by having wide flat body and male long fang.
